Title: An improved method and apparatus for measuring quantities of heat
IPC: G01K17/02
Filed: 1935-05-27
Abstract: 438,699. Measuring heat quantities. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. May 27, 1935, No. 15432. Convention date, May 26, 1934. [Class 97 (iii)] In measuring quantities of heat, e.g. the heat output in a central heating installation or in a cooling process, by the transfer of material due to differences in temperature within a closed vessel, the quantity of material transferred is made approximately proportional to the quantity of heat causing the transfer by providing temperature dependent diffusion resistances opposing the transfer. The substance to be transferred may be a liquid, e.g. sulphur dioxide under pressure, in a condition close to its critical point. In the form shown in Fig. 1, an evaporating vessel 1 containing a liquid 2 has an extended container 3 with a scale 5 at the remote end 4 for measuring the amount of vapour condensed. A temperature controlled resistance to the distillation process is provided by the throttling action of a plate 8 on the end of a bimetallic strip 7. Fig. 2 shows a vessel 3 into which projects the open end 4 of an extended container 5, graduated at the remote end 9. The solid or liquid, e.g. water, 6 to be transferred is covered by a liquid diffusion resistance 7, e.g. ether, ethyl acetate, or iso-amylalcohol, which initially fills the container 5. The substance 6 dissolves in the liquid 7 in amounts proportional to the temperature of the vessel 3, diffuses into the container 5 and there separates. A colouring material such as methyl orange may be used to distinguish the transferable liquid 6 from the confining liquid 7. When the material 6 has all been transferred to the container 5 the apparatus may be reset by swivelling on an axis 2 normal to the heating surface 1, the vessel 3 being partly filled with air 8 so that the rising of an air bubble in the container 5 facilitates resetting. In a modification the temperature dependent resistance to transfer is provided by a gas under pressure, the pressure being further increased with increase in temperature by the thermal expansion of the material transferred and, if desired, of an auxiliary non-transferable substance, e.g. air. Alternatively the blocking medium may be a gas, e.g. nitrogen tetroxide which dissociates with increasing temperature. The evaporation and condensation vessel is preferably arranged within a solid heat conductor provided on the heating body. In a further modification the transferable substance is a gas, e.g. ethane, and the blocking medium a liquid, e.g. water.

Abstract: 1473668 Protective circuits V S SATYANARYANA and B GANDHI 8 April 1974 15525/74 Heading H2K In a protective circuit for disconnecting a load from a power supply, under earth fault conditions or when a human body contacts the live load, comprising an electromagnetic switch S1 operated by a coil K connectable to the power supply by a switch S1 a transistor T1 is connected across the coil K with a resistor R4 connected between its base and the casing of the load L such that when leakage occurs in the casing of the load the transistor T1 is biased to conduct and short out the coil K thus causing switch S2 to open and cut off supply to the load L, and further a current transformer TR1 is connected between switch S2 and the load L to provide shock protection for a human body which contacts the live load the secondary TRs' of this transformer having a capacitor C2 connected across it and the terminals of switch S4, this capacitor also being connected to the base of transistor T1, such that under normal operation with switches, S1, S2 and S4 closed the capacitor C2 carries a charge, but if a human body contacts the live load the voltage in the secondary of TR's increases resulting in an increased charge on C2 which biases transistor T1 to short out the coil K as before to open switch S2. An amplifier or balanced amplifier may be incorporated in the circuit to increase its sensitivity, Figs. 3 and 4 respectively, not shown, two opposed current transformers being used to indicate unbalance due to a human body touching the live load.

IPC: G01F3/22
Filed: 1926-06-23
Abstract: 254,703. Pintsch Akt.-Ges., J. July 1, 1925, [Convention date]. Gas meters.-In a dry gas meter of the type having a single membrane the sudden reversal of the inlet and outlet valves is obtained by the operation of discs 10, 10<1> against the resistance of a spring 11 by means of spring-pawl members 9, 9<1> on a rod 8 engaged by arms 7, 7<1> on pivoted plates 6, 6<1> which are connected by cords 4, 4<1> to the membrane shaft 2. The leverage exerted by the tension of the cords 4, 4<1> increases proportionately to the force required to compress the spring 11 so that the resistance to the movement of the membrane remains constant and the pressure of the gas delivered does not fluctuate. The members 9, 9<1> are automatically disengaged from the disc 10, 10<1> at the end of the travel of the membrane by engagement with stops 12, 12<1> on guide plates 3, 3<1> through which the shaft 2 passes. The mechanism for communicating the movement of the discs 10, 10<1> to the spring lever arms operating the double valves of the gas meter forms no part of the invention. It consists of a lever 25 fitted with a dead-point spring 26 and levers 16, 21 connected to the discs 10, 10<1> by links 13, 19. When the disc 10 is about to engage the stop 12<1> a projection 31 on the lever 16 snaps between two spring-pressed locking pawls 28, 29 on the lever 25, and on the member 9<1> being disengaged from the disc 10 the lever 25 is moved with the lever 16 past its dead-point vertical position. The lever 28 then continues its movement to reverse the valves under the influence of the spring 26. When the disc 10<1> is about to engage the stop 12 a projection 32 on the rod 21 snaps between the locking pawls 28, 29, and on the member 9 being disengaged from the disc 10<1> the movement of the lever 21 restores the lever 25 to its initial position.
